  Parameters
  ----------
  data : ndarray | None
      3D scalar array.
  level: float | None
      The level at which the isosurface is constructed from *data*.
  vertex_colors : ndarray | None
      The vertex colors to use.
  face_colors : ndarray | None
      The face colors to use.
  color : ndarray | None
      The color to use.
  **kwargs : dict
      Keyword arguments to pass to the mesh construction.
docstr: The threshold at which the isosurface is constructed from the 3D data.
